ADJUSTABLE SHELF-BRACKET.

SPECIFICATION forming part of Letters Patent No. 576,939, datedFebruary9, 1897.

Application filed May 4, 1896. Serial No. 590,160. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN BAINES, a citizen of the United States, and aresident of Piqua, in the county of Miami and State of Ohio, haveinvented certain new and useful Improvements in AdjustableShelf-Brackets; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appert-ains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis speciflcation.

My invention relates to two-part adj ustable shelf-brackets, and isdesigned as an improvement upon the invention shown in the LettersPatent granted to me April 12, 1887, No. 361,111. In said invention thebracket comprises two parts, a standard and a bracketarm, the formerconsisting of a rectangular hollow casting the front wall of which isprovided with a vertical slot forming a back which rests against. thewall or other support, the sides and the front vertical flanges and saidback formed with a number of equidistant transverse ribs. The bracketarm is provided with a notched lug at the top and a foot at the bottom,whereby it is held in its adjusted position. In this construction, owingto the greater mass of metal at the back of the standard than at thefront, there is great liability of the casting warping or springing incooling, and thereby breaking. By reason of said warping of the metalthe back of the standard would not fit square against a wall, renderingthe fastening liable to work loose, and the casting is also liable to bebroken in fastening it to the wall or other support.

The presentinvention refers more particularly to the standard, wherebythe above defects are obviated and the quantity of metal used isdecreased, consequently effect-ing a great saving in the cost ofproduction.

The invention consists, essentially, in a standard comprising thevertical sides, having inwardly-extending vertical flanges at the backand front with spaces therebetween, and the front flanges at theiropposite edges 50 formed with equidistant notches.

It also consists in the combination, with such a standard, of abracket-arm formed with a notched lug and a foot, as will be hereinafterfully described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of abracket-standard constructed in accordance with my invention, the arm orbracket-shelf being removed. Fig. 2

is 'a similar view of the arm. Fig.3 is a vertical sectional view, thestandard and arm being connected with each other.

In the said drawings the reference-numeral 1 designates the bracketstandard; 2, the sides thereof, connected together at top and bottom bycross-pieces 3, having apertures 4 therein for the passage of screws orother fastening devices. The said sides at the front are formed withinwardly-projecting vertical flanges 5 and 6, with a space 7therebetween, and the opposite edges of the flanges 5 and 6 are formedwith a number of equidistant rectangular notches 8.

The numeral 9 designates the bracket-arm, formed at its upper end with anotched lug 10 and at the lower end with a foot 12, which engages withsaid notches and holds the arm in its adjusted position.

By forming the standard as above described the back and front containpractically the same amount of metal. Consequently in So cooling thecontraction will be equal and uniform throughout, thus preventingwarping or springing. As the back of the standard is open and thetransverse bars or ribs dispensed with, it will require a less amount ofmetal to construct the same, thereby economizing in their manufacture.On account of the absence of warping the standards can be fitted to awall with less trouble and without liability of breaking in screwin ghome the fastening-screws.

The lug 10 at the upper end of the bracketarm 9 is of a thicknessbetween its upper and lower ends greater than the notches 8 in theflanges of said arm, and in assembling the parts the lugs 10 of thebracket arm are slipped into either the open top or bottom of thestandard and will be prevented from being withdrawn owing to its greaterthickness than the notches. The lug 12 engages with the notches to holdthe arm in any position to which it may be adjusted.

Having thus fullydescribed my invention, what I claim is In anadjustable shelf-bracket, the combination with the standard, comprisingthe vertical sides having inwardly-turned flanges at the front With aspace therebetween and said flanges formed at their opposite edges witha.

series of equidistant rectangular notches and the aperturedcross-pieces, 0f the bracketarn1 formed with a lug at the upper end withopposite vertical notches, said lug being of a thickness between itsupper and lower ends JOHN BAINES.
